Table 1 Differences in biomass and changes in biomass among categories when grown under low and high densities according to the results of linear mixed-effect models. Category, density and their interaction are treated as fixed factors, species nested within category is treated as a random factor.
Variable | Category (C) | Density (D) | C*D | Species (Category) | ||||||||
